IN TRIBUTE—An image of Father Mychal F. Judge, O.F.M., is shown on the banner carried by participants in the 2010 Walk of Remembrance honoring the fire chaplain killed on 9/11. New York Police Det. Steven McDonald, who has been paralyzed since being shot by a robbery suspect in 1986, participates in a wheelchair. This year’s walk will be held Sept. 4.

Archbishop Dolan will celebrate two Memorial Masses on Sunday, Sept. 11, in observance of the 10th anniversary of 9/11.

The first will be at 9 a.m. in St. Patrick’s Cathedral, where numerous Memorial Masses and funerals were held in the days, weeks and months following Sept. 11, 2001.

Then the archbishop will celebrate a Mass at 12:30 p.m. at St. Peter’s Church at Barclay and Church streets across from the site where the World Trade Center towers stood. Cardinal Egan, who prayed and served with victims, rescue workers and families in the aftermath of the attacks, will be the homilist. St. Peter’s, which was damaged by falling debris on 9/11, was a hub for volunteers, firefighters and workers immediately after the attacks.

The archbishop will speak Sept. 8 at a New York Police Department ceremony at Avery Fisher Hall in Lincoln Center, he will lead a New York Fire Department prayer service Sept. 10 at St. Patrick’s Cathedral, and he will speak at a Cantor Fitzgerald memorial service in Central Park Sept. 11. The Cantor Fitzgerald financial services firm lost 658 employees at its World Trade Center offices.

Archbishop Dolan also has granted permission to parishes in the archdiocese to use a Mass formulary fitting for the occasion on Sunday, Sept. 11. Auxiliary Bishop Dennis J. Sullivan, vicar general, suggested in a memo to pastors that the Mass for Peace and Justice, with white vestments, or the Mass for Time of War or Civil Disturbance, with purple vestments, might be appropriate.

In some parishes, a Mass for the Dead might be appropriate as a Memorial Mass for the victims of the attacks, especially parishes with particular ties to individuals who died that day or in churches in close proximity to the site of the attacks, Bishop Sullivan said.

In addition, many churches throughout the city will toll their bells at 8:46 a.m. and 9:03 a.m., the times that the Twin Towers were struck by hijacked planes.

Other memorial events in the archdiocese include:
